These appear to be old, colored glass buttons. There are 30 pieces. Some buttons have holes that were not properly made, so it's possible they were intended as toys for children. Some items have cracks or chips. Some glass buttons have almost no coloring. Please check the photos for the detailed condition and size of the items. Please read and agree to the contents of the profile section. We look forward to your purchase. *Toshio Tada's "Toy Museum 18: Girls' Toys" mentions on page 3 that "Oshajiki (a type of glass game piece) were made from repurposed buttons made of glass, etc." (due to shortages caused by the war). It is unknown whether this item is related.
